DAIRY MACHINE.

Application filed February 19, 1926, Serial No. 89,456, and in GermanyFebruary 28, 1925.

Many forms of small dairy outfits are already known, but withoutexception they are set up of four separate machine, namely: thecentrifuge, churn, butter kneader and motor. In these known arrangementsan important part is played by the driving means, that is belttransmission or similar reducing or change speed intermediate drives,which are expensive to provide. Be-

sides this the space occupied by such means is very great and they canseldom be set up in rural households. All too seldom indeed is a milkroom provided. The present small dairy outfit can be setup in a space ofa square metre.

This invention relates to a combination of motor, centrifuge, churn andbutter kneader, in such a manner, that all the individual machinesare'mounted on or in a single maapparatus. By means of a clutch deviceany desired individual machine can be set in action. In order to keepthe power consumption low and to use a weak electric motor, it isarranged that during churning and kneading, the rapidly rotatingseparator drum acts as regulating and evening flywheel: that is theunavoidable jerking variations in power requirement are evened out bythe momentum of the rapidly rotating flywheel. The accompanying drawingsillustrate two embodiments of a small dairy machine in accordance withthe invention.

Figure 1 shows an outfit with a suspended separator drum.

In Figure 1 a is the pedestal of the machine which carries a kneadingplate I). Beneath this stands a churn c. To the right above is a drive,housing cl. Onv this is screwed a motor 6. The armature shaft f of themotor is of worm form opposite a worm wheel g and meshes therewith. Inthis way a shaft h is driven. In addition a toothed wheel 2' is mountedon the armature shaft and meshes with a pinion is. This carries a drivespindle Z which rotates a separator drum m through a coupling. n is acollecting cover which leads ofi' separately the chine pedestal and thusform only a single cream and skimmed milk. The whole milk to be skimmedis poured into a bowl 0 and is led into the drum m through a pipe p.

The shaft 71. carries a toothed whee], g which meshes with teeth 7' inthe kneading table 3) and thus drives it. There is also a bevel wh;el son the shaft h, which meshes with a bevel wheel t and thus drives thespindle u provided with a couplin for the shaft '2) of the churn beater4 whic is thus rotated. I

A spindle w is borne in a vertical arm to of the pedestal a, on whichspindle rotates a kneading roller 2. This is driven b a toothed wheel ameshing with a toot ed crown 3 on the kneading plate I).

The individual machines are put in and out of gear by longitudinallysliding the shaft h by a screw j engaging in'a thread 3 in the drivehousing all.

Figure 1 shows the machine with the churn in gear. The separator drumruns during churning and kneading. If the churn is to be put out of gearthe screw j is so turned that the shaft 72. moves to the right. Thewheel pair st goes out of mesh and the machine is now ready forseparating, while thechurn and kneader remain Sta-- tionary. By furtherturning the screw the shaft h moves still further to the right, so thatthe wheel 9 mesheswith the teeth 'I' and the kneading plate is rotated.At the same time the roller 2 is also driven through the crown y andwheel 2.

A hand crank can be secured to the shaft 71. in front of the screw j foruse in case of interruption in the supply of electric power.

In Figure 2 the same arrangement is shown with a standing instead ofsuspended separator drum. The action is the same as that abovedescribed.

What I claim as my invention is 1. In a small dairy outfit embodying apedestal, a kneadingplate and achurn carried thereby, a motor, and aconnection between the motor and the kneading plate and the churn,the'combination with such elements of a separator drum arranged to runduring churning and kneading and to serve as a regulatin fly Wheel tobalance the churn and the neader.

2. In a dairy machine, a butter churn, and its shaft, a butter kneader,a motor and its shaft, a horizontal shaft with gearing between the motorshaft and the horizontal shaft, operative connections between thehorizontal shaft and the shaft of the butter kneader and the churn,shiftable connections 1 between the butter kneader and the churn, saidconnections embodying a Worm Wheel having teeth sufficiently long topermit of the shifting of the horizontal shaft to drive the desiredelement irrespective of the other. 1 In testimony whereof I aflix mysignature.
